TO ALL WHOM IT MAY CONCERN:

Be it known that I, WALTER H. Fonsnsn, of thecity of Bufi'alo, county of Erie, and State of New York, have invented certain new and useful lmprovemen'ts in Numbering or Paging-Machines; and I do hereby declare that the following is a full, clear, snd'cxnet description thereof, reference being had to the accompanying drowihgs, making e port of this specification.

The nature of this invention consists, first, in the application, to the rotating wheels or disks of n numbering machine, of a registeringher or pawl, striking radially, o neerly so, into 0. series of externalregistering notches, out in said wheels, said pawl being raised out of said notchesjust before, and striking therein-jusisinfter each movement or change of the numbering-disks, thereby bringing the figured feces of the several-disks inio }38If9$i7 register or alignment; second, constructing the registcringrpawl with a system of steps, when the snme is made to Work in combination with a, pawl, giving motion to the numbering-disks, by msystem of siege similar but reversed, so that ivhen this movement-pawl engages the first or unit-disk, the register-pawl releases both, and so on throughout the series of disks constituting the numbering-machine, the registering-pawl alvinys entering and holding all of the disks after each change; third, in ihc const 'uc'tionof certain mechanism for giving the requisite movements to the disk-changing pawl. In the accompanying drawings Figure I is a side elevation of my improved numbering-machine.

Figure llis n'revei'sed side elevation, showing mechanism for operating disk-changing pawl,

Figure Iii. is a sectional plan, and I Figure IV detail view of registering-pawl.

Like letters represent like psrtsin each of the figures.

A A A A A represent the wheels or disks comprising the machine, each disk havingten projecting arms, a upon which are engraved successively the nine digits and cipher. They are arranged side by side, npcn eshnft, B, in a frame, B. The left-hand disk/Ads the units disk, the next, A ihe tens, the next, AS, hundreds, and so on through the series; The disks-hove two sets or series, of ten each, of external notches out in them, the one set, lettered C, being shnllow, end for the changing-pawl to work in. One of this set-cf notches, lettered C, is cut' deeper than the rest, for purposes which will hereafter appear. The other set,- lettelfcd D, including a. half notch,'.D','are all cut deep, the same as C, and are forthe registeringpnwl-to work in, E represents the chnngingpewl, by the "engagement of which with the notoh'es (l, the required movements are given to the disks. This pawl isconnected ton side plate or arm, E, hung at its inner end upon the shaft B, and slotted, as shown at e, so that the pawl may be given an inward radial movement, to engage the notches Q of the disks, on ensuing downward movement concentric with the disks, sufiicient to carry the disks forward one-tenth of a. revolution, an outward redial movement "to withdraw the pawl from the notches, and upward movement to return it to the starting-point. The mechanism for producing this in, d .own,oi1t, and up movement of the pawl will be described further on, The entering edge of the pawl is out into a series oi' steps, a the first step, or highest, being in line with units disk, the next. step in linc'with tensi disk,the next with hundreds disk, and so on. The height of each of these steps isn trifle greater then the depth of the notches (l, and the height of all comliinedjust equal to that of thedeep notch G. Owing to this arrangement of the steps, when the inward movement of the pawl is directed to either of the shallow notches U, of the units disk, the first step will engage said units disk, and it only, so that only the units disk will he carried around in its ensuing do\vn word movement, but when it is directed to the deep notch C of the units disk, it may enter farther, and cause its second step to engage the tens disk, and so carry both the units and tens disks fox-ward. And in like -manner, when the deep notch of the units disk is in line with the deep notch of the tens disk, it may enter still farther, and cause its third step to engage the hundreds disk, and so carry both units, tens, and hundreds disks forward, and so on through the whole series of disks. Now, since each disk'has only one of the dean notcl1cs,-O, it follows that the units disk must make nine movements, one-tenth of a revolution each, before. the pawl will engage and move the tens disk, and that the tens disk must make nine movements before the pawl will engage and move the hundreds disk, and so through the series. The relative position of the deep notches to the linc'of figures recording the movements of the disks, in this case shown at F, must be such that they will be in position to receive t'he' pawl when the figures 9 reach said line, so that the ciphers. willrcome into said line with the recording figure of the next higher disk. For instance, when the 9 of the units disk reaches this line, its deep notch must be in position, so that the pawiwill engage the tens disk,'and in Bringing the'() of the units disk into place, bring also the digit of the tens' wheel, recording the numher of tens 6' units disk has counted. H t I Having thus described thcoperation of the changing-pawl, I will now describe'the registering-pawl iii its combined operation therewith.

G represents the registering-pawl, attached to one arm of a lever, G, which is hinged to the frame B, al a'point, so located that the pawl maystrikc radially,'or nearly so, into the registeringmotches D. The entering edge of this-pawl has a system of steps, gflsimilar to those of the changing-pawl E/but rversed in position, that is, the lowest step entering the units disk, the next higher step the tens wheel, an d so on. Thercgistcring notches are of such depth that the pawl may strike into them until its lowest step enters and holds the units disk. The other arm of the lever-G extends towards the changing-pawl, and has a stud-pin, g, entering a slot, 9 in theside plate E, to which the changing-pawl is attached,,sc that the inward and outward movemeats of the changing-pawl are communicated to the registering-pawl, whereby, when the changing-pawl enters the units disk, the registering-pawl is raised out therefrom, so that the units disk may take its forward moremcnt, upon completion of which the registering-pawl drops into the next notch and holds the units disk until it'is again released by the movement of the changing-pawl. In like manner the engagement of the changing pawl with 'the units and tens disks, or units, tens, and hundreds disks, 8m, will raise the registering-pawl therefrom and release/them for their forward movement. It thusfollows that theregistering-pawl releases su'ch disks as are engaged by the changingawl, but retains its hold'upon'all the others, so that at all times the 7 two pawls together have positive hold of all the disks, and that the'registering-pawl, after each movement of the disks, strikes through the whole series, and brings them into perfect register and alignment. half notch, I)", is provided for-the register-pawl, so that all of the wheels not required for the commencing figure may be set out of line with the recording place, they being broughtinto place by the action of the changing-pawl, as willa be readily understood.

The mechanism for effecting the in, down, out, andnp movement of the changing-pawl, is as follows:

H represents a. radial arm, swinging'npon the shaft B, and slotted the same as the side plate E. This and has a right-angled bend, H, at its moving end, to which the side plate E is connected by the hook H, a spring, H being interposed between said b'end H and the changing-pawl. I represents a slotted cam, on the shaft B, at the sine of the arm H, whicharm carries the 'stud I, working in the slot of, the cam, so that a downward movement of the cams draws the arm H inwardly, until the upper end of the canbslotstrikes the stud,-when the inwnrd movement of the arm is changed to a'downward movement: Theupward return movement, of the cam first throws the arm outwardly, until the bottom of its slot strikes the stud inthe arm, and its outward movement ischanged to an upward movement to the starting-point. The arm is held and; guided in its inward and outward movementszby a spring-pin, J, striking into notches J, and in a fiiied plate, 3', said notches being in such position as to cause the changing-pawl, as it receives movement from the movement of the arm, to properly enter and leave the notches-in the disks. I

i The in and out movementof the arm is uniformly sufiicient to cause the changing-pawl to engage allot the disks, when their"'deep hotches come together, so that the changing-pawl will always be carried into the notches of one ormorc of the disks, or until it strikes the bottom of a notch, when the yielding of the interposed spring H will allow the arm to complete its inward movement. Thisnumbering-mechauism being attached by'its frame 13 to a vibrating-arm, K,'or to the reciprocating cross-head of a printing-press, and a connection made by the rod K from apermanent arm, K with. the cam, each upward movement of the arm K will cause the cam to givetho in and down movement to the arm H, and through it to the changing-pawl, to operate the disks, while each upward movement of the arm'K will give thereturn out and up movement to said parts. By a duplication of the arm H, com I, and fixed plate .1, the bend, H, being extended and connecting the two arms H together, any desired number of independent machines, secured to a croSs head'in line with each other, .as is common in presses forprinting and numbering coupon railroad-tickets, and between said arms, may be operated at the same time by simply hooking the side platesE' ofeach one into the bar H.

Having thus described the construction, and operation of myinvention, what I claim, and desire to secure by Letters Patent, is-- I x 1. A registering-pawl, G, striliing radially,' or nearly so, into the (internal registering-notches D of 'the disks, after each movement thereof therdby bringing said disks into strict alignment.

Y 2. The system of steps, 9 on the rcgitering-pawl G, working in combination with the steps of the changingpawl E, substantially as set forth. r

'3. The mechanism, co'nsistiiig of the cam I, arm H, and fixed plate J, or the equivalentthereof, for giving the in, down, out, and up movement to the changing-pawl E, as and for the purpose set forth. I
